Add a To Do List In game

Add a to do list where we can note down different things from what we are planning to do and so on

It'd be really great if it could just fit into the existing 'tutorials' UI. That's kind of useless after early game, and fits in really well with my workflow, as I currently use the alerts and research log as a pseudo todo list, but thats only limited to new research and alerts I set up. Sometimes I'll make a t1 storage somewhere with a descriptive name and empty alarm, but then my 'todo list' takes up a bunch of physical space (and resources!). It'd be nice to cut out this step!
